MARTINEZ-PUC, Jesús Froylán; MEDINA-MEDINA, Luis A.; LEAL-HERNANDEZ, Marisela  and  MERLO-MAYDANA, Flavio Eudaldo. Frequency of Varroa destructor, Nosema spp and Acarapis woodi in commercial colonies of bees (Apis mellifera) in Yucatan, Mexico. J.Selva Andina Anim. Sci. [online]. 2015, vol.2, n.1, pp.2-12. ISSN 2311-3766.

Today it has been observed that diseases affecting bees (Apis mellifera) have caused significant economic losses in the European continent and in parts of the United States due to high mortality in honey bee colonies without a cause apparent, which is known as the syndrome of depopulation of hives. It is noteworthy that this mortality is not yet presented in Yucatan. In order to determine the frequency and levels of infestation Acarapis woodi and Varroa destructor, and the frequency and levels of infection Nosema spp. commercial colonies of bees (A. mellifera) in Yucatan, was collected from June to December 2006, a total of 165 samples distributed in 13 towns of Yucatan. V. destructor frequency was 63.6%, with an average level of infestation of 2.85 ± 0.79 (mites / 100 bees). The frequency of Nosema spp. was 81.8%, with an average infection level = 1'234000 ± 118000 (spores / bee), the presence of A. woodi in the samples analyzed was detected. The existence of an association between V. destructor and Nosema spp was observed. (X² = 6.53, df = 1, p = 0.01).

Keywords : Often; Apis mellifera; Varroa destructor; Nosema spp; Acarapis woodi; Yucatán.
